The one orchid ooth I've had so far I kept in a 32 oz delicup, attached to the lid. Lid was sealed with packing tape and a wet paper towel was place in the bottom. Misted once a week. Hatched about 50 nymphs after 5 weeks in the upper 70s to 80F over 3 days (only 3 on the 3rd day).
About 6-8 dropped dead over the next couple days in the mesh container they were moved into. A couple did not get out of the ooth well and also died.
